Units explained
Square Nanometer
A square nanometer is a metric unit of area equal to 10⁻¹⁸ m² (1 nm × 1 nm). It is the standard unit in nanotechnology and surface science for expressing the area of nanoscale structures.
Derived by squaring the nanometer (10⁻⁹ m). The nano- prefix comes from the Greek 'nanos' (dwarf).
Square nanometers are used to express the surface area of nanoparticles, the footprint of single molecules adsorbed on surfaces, and the active area of nanoscale electronic devices.
Nanometer adopted into SI in 1960; widespread use in nanotechnology grew through the 1990s and 2000s.
Square Picometer
A square picometer is a metric unit of area equal to 10⁻²⁴ m². It is used at atomic and molecular scales.
Derived by squaring the picometer (10⁻¹² m). The pico- prefix comes from the Italian 'piccolo' (small).
Square picometers appear in computational chemistry, surface science, and X-ray crystallography when discussing atomic cross-sections and very small surface patches.
SI prefix pico- adopted in 1960.
Square Nanometer to Square Picometer conversion formula
The relationship between square nanometers and square picometers:
To convert square nanometers to square picometers, multiply the value in square nanometers by 1000000.0000000001. To reverse, multiply square picometers by 1e-6.

Step-by-step: convert square nanometers to square picometers
- Write down the value in square nanometers (nm²).
- Multiply that value by the factor 1000000.0000000001.
- The product is the equivalent value in square picometers (pm²).
- To reverse, multiply the square picometer value by 1e-6.
Worked examples
Example 1 — Convert 1 nm² to pm²:
1 × 1000000.0000000001 = 1000000.0000000001 pm²
Example 2 — Convert 100 nm² to pm²:
100 × 1000000.0000000001 = 1e+8 pm²
Real-world example — Wavelengths across the spectrum
Optical and atomic-scale phenomena are routinely cross-converted between sub-micron units. A photon of wavelength 800 square nanometers can be re-expressed in square picometers for direct comparison with another instrument's calibration data sheet.
800 nm² × 1000000.0000000001 = 8e+8 pm²
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 square nanometers) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 nm² × 1000000.0000000001 = 2000000.0000000002 pm²
